Specification of Letters Patent.

Patented Dec. 1L2, 1916.

Application filed April 21, 1916. Serial No. 92,649.

To all whom it may concern:

Be it known that I, PEARL M. HALLER, a citizen of the United States,residing at Bay Qty, in the county of Bay and State of Michigan, haveinvented certain new and useful Improvements in Fire-Extinguishers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention'relates to new and useful improvements in fireextinguishers and the principal object of the invention is to provide anextinguisher which will effectively spread and deflect the extinguishingliquid over the burning area so as to readily extinguish the flame.

Another object of the invention is to provide an extinguisher which isautomatic/in its operation so that when the same becomes heated up. toor beyond a predetermined point it will automatically be set inoperation.

A further object of the invention is to provide an extinguisher whichmay be hung from a suitable point within a room or building andsuspended in such a manner that the outpouring'liquid will be directedagainst a revolving deflector plate which will effectively separate andscatter the liquid over a wide area.

With these and other objects in view, the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawing, in which Figure1 is a side view partly in section of a fire extinguisher constructed inaccordance with this invention, and Fig. 2 is a bottom plan view of Fig.1.

Referring to the drawing the numeral 1 designates the tank or containerfor the extinguishing liquid which is provided with a closure at eachend and the upper end closure is provided with a pair of spaced ears 2for the reception of hooks or hangers by means of which the device issuspended. A filling valve 3 is provided centrally of the upper endclosure and provides a means for admitting the extinguishing liquid. Asuitable outlet opening 4 is formed in the lower end closure of the tank1 and is surrounded by a neck 5 to which the cap 6 is attached. This cap6 is formed of celluloid or any suitable highly inflammable mate rialwhich will open the passage through the neck when it becomes extensivelyheated or when the flames reach the same. It will thus be seen that theextinguisher tank will automatically be opened to permit the contents toflow out through the neck.

Secured to the under side of the bottom end closure of the container aresuitable bosses 7 in which are threaded the depending arms 8 whichcooperate with the plate 9 in forming a supporting frame for thedeflector. This plate 9 is formed with a central depression 10 forming abearing for the shaft 11 the upper end of which projects through anopening 12 in the bearing plate 13 which is supported intermediate theupper and lower ends of the arms 8 and is provided to hold the shaft ina vertical position as illustrated in the drawings. Secured to the upperreduced portion of the shaft 11 is the deflector designated by thenumeral 14 which consists of a plurality of deflector blades which areconstructed around a hub in the manner similar to the ordinaryconstruction of screw propellers.

In use it will be seen that upon the burning through or melting of thecap 6 the contents of the tank or container 1 will flow through the neck5 and out through the opening in the lower end thereof and be forciblydirected against the deflector 14; thereby causing the same to revolveand scatter the outfiowing liquid over a wide area. It will beunderstood that the force of the outflowing liquid is obtained by theuse of air pressure as the tank is first filled to a predeterminedheight with the extinguishing liquid and then air forced into the sameand it will thus be seen that the extreme pressure of the outflowingliquid against the deflector 14 will cause the same to rapidly revolveand give a much more effective operation than would otherwise beobtained.

While in the foregoing there has been shown and described the preferredembodiment of this invention. it is to be understood that such changesmav be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the appended claim.

What is claimed is A fire extinguisher comprising a tank adapted to holdliquid under pressure. a

pair of supporting ears at the upper end of provided with an outletopening, a neck surrounding said outlet opening, a cap of highlyinflammable material for closing the lower end of the neck, hollowinternally threaded bosses formed on the bottom of the tank, armsthreaded into the bosses, a plate connecting the lower ends of the arms,a cooperating plate mounted intermediate the ends of the arms, a shaftjournaled between the plates, a rotary deflector mounted on the upperend of the shaft and adapted to be automatically rotated by theoutflowing contents of the tank and an inlet valve in the upper end ofthe tank through which the liquid is passed when the same is being,filled.

In testimony whereof I afiix my signature in presence of two witnesses.
